They are very coy about pricing. The PCI-e card looks interesting,
but it you have to ask how much it costs ...

if you want to see an interesting example of the kind of machine we had in
mind for NIX:

4 superscalar risc-v cores, and about 1000 basic scalar cores.
Pretty interesting.

I checked in execac system call support this morning. not tested.
I am bringing this back to life because I hate to see it lost. 9front is a
good vehicle and, once it is in, keeping it alive as a fork or branch is
doable.
There are several ideas in here that may be worth keeping.
The idea of "cor
I never really understood what this was supposed to be. seems like an
interesting idea. very asymmetric multi-processor stuff.
what do you all think we should do?

Hey Ron,
Looks like you didn't check in the implementation of execac.
Happy February :)

that's the first attempt to call an icc in quite a while.
one weird thing: either qemu does not implement mwait (unlikely) or we're
not enabling it (likely)
I'll see.

It panics in acmmuswitch
So there's something for someone to chew on.
I've been able to ditch a bit of NIX infra that is
FWIW, that boots in qemu. But I've not tested turning on an AC yet.

Hi all,
I finally found some time to get my dev environment setup on 9front running
on QEMU on macos. (huzzah!)
Now, I can start poking around, reading code, and hopefully contributing
something useful. :-)
Cheers,
Chris

The startup IPI is handled by mpstartap and lapicstartap.
Otherwise,
apropos this, I just now pushed a fixup for acmmuswitch that's better.
we're getting pretty close to 'turn on an AC and watch it burn' point.

from my point of view, what is lacking in NIX is that it's not integrated
into a living code base, rather it is its own thing. That means it can not
take advantage of the last 14 years of plan 9 improvements and bug fixes.

I created an issue on the GitHub but I figure using the mailing list was more

Is there already a list of things to do? Shall we maintain a file to track
tasks needing to be completed?
I would like to at least be able get a handle on what is still lacking in
